High Speed Flows and Slow Speed Solutions – An Introduction to Under-Expanded Jets Modelling Challenges

Introduction Fluid jets are found in many engineering applications including rocket nozzles and cooling devices, but may also arise due to accidental leaks. When the fluid is a gas, relatively low pressures are required for the jet to reach the speed of sound (Mach 1) at the exit of the nozzle. As such, it’s important […]
